IMPROVEMENT IN THE MANUFACTURE 0F ENAMELED BRACELETS.

Specification forming part of Letters Patent No. 91,604, dated June 22, 1869.

To all whom it may concern:

Be it known that I, ARIEL CODDING, Jr., of

North Attleborough, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements in the Manufacture of Enameled Bracelets and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a perspective view of my improved bracelet. Fig. 2 is a cross-section, showing the position of the parts before the iianged edges of the inner plate are bent down upon the enamel.. Fig. 3 is a cross-section'of the bracelet complete. Fig. 4. is a cross-section in red, showing the method heretofore followed in making enameled bracelets.

Similar letters of reference indicate corresponding parts.

The object of this invention is to provide a more simple and inexpensive method of manufacturing a kind of bracelet called enameled bracelets.77 l

The process of manufacture consists, in general terms, in uniting the inner plate with the enameled plate, by means of two flan ged edges on the inner plate, the said flanged edges being bent upon the fillet of enamel or enameled plate laid around and against the inner plate,

within the flanged edges of the latter.

Heretofore it was the custom to strike up a convex plate, e, Fig. 4, with a recess in its convex surface, in which the enamel fwas inlaid, and to solder on the inner plate, g, as shown. This method involved considerable skill and time in putting in the enamel, and the bracelet so made was liable to become damaged by its peeling out of the recess.

By my improved method, however, these objections are obviated.

In the drawings, a is the inner plate, of

sheet metal, formed by any proper tool or ma- 4 chine with upset or 4flanged edges c c. d is an enameled plate, of sheet metal, formed with a concavo-convex cross-section by means of any proper tool, or by runnin git through suitable rolls. flanges c c,'and the latter are pressed down against the enameled surface, as shown at Figs. 3 and't. A

Instead of an enameled plate of sheet metal a solid iillet of any suitable enameling matter having a plano-convex cross-section may be substituted, and the edges c c pressed down upon it, as before described.

By means of my invention I am enabled to employ an enameled plate of metal or any solid substitute or imitation of the same, as hard rubber and other like matter.

The edges c c are bent down in practice by running the -two plates through a semicircular openin g through a plate, or through any other suitable device.

The plate a may be of gold or a plated imition of bracelet be obtained as when enameled plates are used.

I claim as new and desire to secure by Letters PatentrIhe enameled bracelet formed by the sheetmetal base-plate a, havin g longitudinal lian ges c c, and the enameled concave-convex plate el,

adapted to lit between and to be secured in place by the flanges c, substantially as described, for the purpose specified.
